(接上期)除此之外,我们可以在具体的运算中掌握一些常用方法进行公式化的思考,以大大增加胜算的可能.窍门1:选择最后一步运算是乘法,把4个数凑成24的两个因数.(1)组合一个因数法.先固定一个数为24的因数,再把其他3个数凑成24的另一个因数.如:2,5,7,8,先固定2,余下的5,7,8能凑成
(Continued from the previous period.) In addition, we can use some common methods to formulate thinking in specific calculations to greatly increase the odds of winning. Tip 1: Select the last step of the operation is multiplication, and make the 4 numbers into 24 Two factors. (1) Combine a factor method. First fix a factor of 24, and then make up the other 3 numbers into another factor of 24. For example: 2, 5, 7, 8, first fix 2 and the rest 5,7,8 can make up
